摘　　要：室内毒力测定表明，络氨铜锌水剂对供试的几种病原菌均具有不同程度的毒力，１２００倍以下浓度对水稻稻曲病菌（Ｕｓｔｉｌａｇｉｎｏｉｄｅａｖｉｒｅｎｓ）厚垣孢子、黄瓜霜霉病菌（Ｐｓｅｕｄｏｐｅｒｏｎｏｓｐｏｒａｃｕｂｅｎｓｉｓ）孢子囊、莴苣灰霉病菌（Ｂｏｔｒｙｔｉｓｃｉｎｅｒｅａ）分生孢子萌发抑制均达１００％；１５０倍液对白菜霜霉病菌（Ｐｅｒｏｎｏｓｐｏｒａｐａｒａｓｉｔｉｃａ）的孢子囊萌发抑制率为１００％；３００倍液对黄瓜白粉病菌（Ｅｒｙｓｉｐｈｅｃｉｃｈｏｒａｃｅａｒｕｍ）分生孢子萌发抑制率为１００％；６００倍液为９１．４３％；１２００倍液时为８５．６９％；２４００倍液为７７．３９％。田间小区防效试验表明，络氨铜锌水剂５００倍液对水稻稻曲病的相对防效为７８．５４％；６００倍液对大白菜霜霉病的相对防效为４５．１０％。Roomvirulence experiments showed that cheshunt and zinc compound was an effective agent for inhibiting the germination of the chlamydospores of false smut of rice (Ustilaginoidea virens)、sporangia of cucumber downy midew(Pseudoperon spora cubensis)、conidia of lettuce gray mold、sporangiof cabbage downy midew(Peronospora parasitica) and cheshunt and zinc compound liquid had the relative control effect with 78.54% on false smut of rice and six hundred times with 45.1% on cabbage downy midew.
